"night fever" is the second polish of the trio that I have bought. It's part of the 'Sand Nails' products from the standard product range. A deep black with multi-coloured confetti, silver-coloured glitter and silver-coloured shimmer. The sand effect is very noticeable when the polish is just a few hours old (on the nails) but it feels more like a bumpy glitter polish after a day because the effect just vanishes due daily activity. Two layers which are not super-fast drying but it's okay. The application was easy (I like the brush). "night ever" turns into a real gem with a top coat (I used "gel-look topcoat" by essence.) because the silver-coloured shimmer is even more noticeable now.
